[PATCHSET v24.0 0/4] xfs: detect incorrect gaps in inode btree

Hi all,

This series continues the corrections for a couple of problems I found
in the inode btree scrubber. The first problem is that we don't
directly check the inobt records have a direct correspondence with the
finobt records, and vice versa. The second problem occurs on
filesystems with sparse inode chunks -- the cross-referencing we do
detects sparseness, but it doesn't actually check the consistency
between the inobt hole records and the rmap data.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything. Enjoy!
Comments and questions are, as always, welcome.
